An image processing apparatus includes circuitry configured to receive a designation of a to-be-corrected color that is a process color or a special color different from the process color and is to be corrected; identify, on the basis of the designation, a tone correction pattern, and generate rendering data of the tone correction pattern to be used for forming an image on a recording medium; obtain a standard value of the to-be-corrected color; and correct the to-be-corrected color on the basis of a difference between a color measuring result obtained from measuring a color of the image, of the tone correction pattern formed on the recording medium and the standard value.
Legal claims defining the scope of protection, as filed with the USPTO.
1. An image processing apparatus comprising: circuitry configured to receive a designation of a to-be-corrected color that is a process color or a special color different from the process color and is to be corrected; identify, on the basis of the designation, a tone correction pattern, and generate rendering data of the tone correction pattern to be used for forming an image on a recording medium; obtain a standard value of the to-be-corrected color; and correct the to-be-corrected color on the basis of a difference between a color measuring result obtained from measuring a color of the image of the tone correction pattern formed on the recording medium and the standard value, wherein the image processing apparatus further comprises: a display unit, wherein the circuitry is further configured to cause the display unit to display, as choices of combinations for the to-be-corrected color, to select “CMYK” or “CMYK+Special color”, and not to select a choice of only the special color, when a special color of a fluorescent color is used.
2. The image processing apparatus according to claim 1 , further comprising: a display unit, wherein the circuitry is further configured to cause the display unit to display, as a choice or choices for the to-be-corrected color, the process color, the special color, or a combination of the process color and the special color.
3. The image processing apparatus according to claim 2 , wherein the special color includes white.
4. An image processing system comprising: receiving circuitry configured to receive a designation of a to-be-corrected color that is a process color or a special color different from the process color and is to be corrected; rendering data generating circuitry configured to identify, on the basis of the designation, a tone correction pattern, and generate rendering data of the tone correction pattern; tone characteristic obtaining circuitry configured to obtain a standard value of the to-be-corrected color, image forming circuitry configured to form an image of the tone correction pattern on a recording medium; and tone correction circuitry configured to correct the to-be-corrected color on the basis of a difference between a color measuring result obtained from measuring a color of the image of the tone correction pattern formed on the recording medium and the standard value wherein the image processing system further comprises: a display unit, and displaying circuitry configured to cause the display unit to display, as choices of combinations for the to-be-corrected color, to select “CMYK” or “CMYK+Special color”, and not to select a choice of only the special color, when a special color of a fluorescent color is used.
5. A non-transitory recording medium storing a program, when executed by a processor of an image processing apparatus, causing the processor to implement an image processing method, the image processing method comprising: receiving a designation of a to-be-corrected color that is a process color or a special color different from the process color and is to be corrected; identifying, on the basis of the designation, a tone correction pattern, and generating rendering data of the tone correction pattern to be used for forming an image on a recording medium; obtaining a standard value of the to-be-corrected color; and correcting the to-be-corrected color on the basis of a difference between a color measuring result obtained from measuring a color of the image of the tone correction pattern formed on the recording medium and the standard value, wherein the method further comprises: causing a display unit to display, as choices of combinations for the to-be-corrected color, to select “CMYK” or “CMYK+Special color”, and not to select a choice of only the special color, when a special color of a fluorescent color is used.
6. The image processing apparatus according to claim 1 , wherein the circuitry is configured to cause the display unit to display to select “CMYK”, “CMYK+Special color” or “Special color only” when the special color excluding the fluorescent color is used.
